I just updated to mesa-18.3.1 earlier today. A couple of things I found after
reading this thread:
1. Package libtizcore was not found. We don't have this mentioned and I
don't know what it does. I did find
https://github.com/tizonia/tizonia-openmax-il/tree/master/libtizcore but there
is no documentation.
There is only one file in src/. It is a 1900 line .c file. A comment:
* This library implements the base OpenMAX IL Core infrastructure, as
* specified in the standard.
But I don't know what that means. Google points to
https://www.khronos.org/openmaxil but a very fast scan indicates to me that we
don't need it.
2. Using PYTHON=python3 in the configure works. If P2 is not present, then
I suspect that it would pick it up automatically, but I've not tried.
2a. The make log only references python3 once.
3. It does look for mako.
4. We could switch to meson.
A couple of remarks about mesa+P3:
- I think I will not be able to test building mesa with only P3 available. The
reason is that I need llvmpipe, and that LLVM seems to require P2 (although
some work seems to have been done in order to support P3 (see e.g. [1] and
[2]) for some time now.
Update: according to the documentation [1], Python seems to be only required
for tests. As anybody tested that Python is not needed if the tests are not
run (and/or built, that is P2 could be needed as soon as -DLLVM_BUILD_TESTS is
ON)? If this is the case, we could make P2 optional for llvm, remove the
"-DLLVM_BUILD_TESTS=ON" flag, and expand the test section to mention this flag.

I am getting ready to do a new build on my laptop. Normally I don't
need llvm for mesa on that system, but I can do the build and test
without P2.
I plan to start later today or tomorrow.
